RAILROADQFRGG.

Specification of Letters Patent.

Patented .1 uly 16, 1912.

Application filed February 8, 1912. Serial No. 676,225.

To all whom it may concern:

Be it known that I, CHARLES A. ALBEN, a citizen of the United States, residing at Steelton, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Railroad-Frogs, of which the following is a specification.

This invention relates to that class of railroad frogs wherein the point portion and one or both of the wing rail portions of the frog are formed in a single casting of hard metal such as manganese steel.

The object of my invention is to provide a frog of such construction that the point portion and one or both of the wing rail portions thereof may be formed in a single hard metal casting in which the metal may be more evenly distributed throughout the parts of the casting than heretofore in which the desired strength may be obtained from a smaller amount of metal than heretofore and in which the point portion and one or both of the wing rail portions of the frog may be supported by a common base forming a part of the casting, so that when the base of the casting rests upon a railroad tie, the point portion as well as the wing rail portion or portions will be supported directly beneath the same by the tie.

A. further object of the invention is t o construct the parts of the casting to provide a suitable cavity or cavities below the flangeway or tlangeways of the frog for the reception and retention of a suitable filler composition such as an asphaltic concrete to form a bottom or floor portions for the tlangeway or flangeways, thereby avoiding the necessity of machining or finishing hard metal in'these floor portions.

Tith these objects in view, the invention consists in the novel features of construction and combinations of parts hereinafter fully described and particularly pointed out in the claims.

ln the accompanying drawings, illustrating my invention: Figure 1, is a plan view of a railroad frog, showing one form of embodiment of my invention. Fig. 2, is a lon! gitudinal section thereof, on line 2 2 of Fig. 1. Figs. 3, 4, 5, 6, 7 and 8 are transverse sections, on lines 3 3, 4 4, 5 5,

6 6, 7 7 and 8 8, respectively, of Fig. 1.

Referring to the drawings, 9 designates the threadeforming point portion of the frog and 10 the laterally disposed wing rails diverging from the frog throat 11. `The usual iiangeways 12 are formed between the wing rails 10 and the point portion 9 for the reception and guidance of car wheel flanges as the wheels pass over the frog; and the free ends of the wing rails 10 are flared outwardly, at 13, as usual, to direct the wheel flanges to the flangeways 12 as the wheels pass over the frog in the direction toward the point end of the point portion 9.

In accorda-nce with my invention the wing rail portions 10 and the point portion 9 are formed in a single casting of hard'metal, preferably manganese steel, and the detailed construction of the main body of the casting forming the point and wing rail portions is as follows: 14 designates a liat base adapted to rest on underlying cross ties throughout the width of the main body of the frog. The point portion 9 comprises a web 15 rising from the central portion of the base and extending longitudinally of the frog, and a head or tread 16 formed on the top of the web 15. The head 16 is made tapered and increases in width from the frog point to the heel end of the point portion, and a slightdistance back of the frog point the head 16 extends laterally from Veach side of the web 15, the lateral extensions increasing in width as the point portion widens. Each vwing rail portion 10 comprises a web 17 rising from one side of the base 14 and extending longitudinally of the frog, and a head or tread 18 formed on the top of the web 17 and extending laterally therefrom on each side thereof.

In order to properly brace the point portion 9 and wing rail portions 10 against lateral strain and to support theheads 16 and 18, respectively, thereof, I form ribs or webs 19 and 20 in the casting. The web 19 eX- tends transversely of the frog between and `connects the wing rail webs 17, and the web also extends between and connect-s the bot toms of the inner sides of the wing rail heads 18 and the base 14. The webs 20 eX- tend transversely between and connect the wing rail webs 17 and the point portion `web 15, and the webs 20 also extendvertically between and connect the bottoms of the inner sides of the wing rail heads 18 and the base 14, and the webs 20 also extend vertically between and connect the bottom of the head 16 and the base 14 where the head 16 extends laterally from the web 15. Leading from the heel end of the point portion 9 are the usual diverging track rails 21, and leading from the ends of the wing rails 10 adjacent the frog throat 11 are the usual diverging track rails 22. of the casting are suitably formed, as shown,

to receive and lit the ends of the rails 21 andy theflangeways 12 and which is held in place by the heads 16 and 18 extending over the same.' This concrete filler also serves as foot guard where needed.

I claim:

j 1. In a railroad frog, a steel casting forming'a base plate, a point portion and av wing rail adjacent one side of the point portion, said wing rail comprising a longitudinallyextending web risingV from the base Vplate and having a head formed on the top thereof and extending laterally therefrom.

2. In a railroad frog, a steel casting forming a base plate, a point port-ion and' a wing rail adjacent one side of the point portion, said point portion comprising a longitudinally-extending web rising from the base plate and having a tapering head formed on the top thereof and extending laterally therefrom.-

3. In a railroad frog, a steel casting forminga base plate, a point portion and a Wing rail'l adjacent one side of the point portion, said wing rail comprising a longitudinallyextending web rising from the base plate and having a head formed on the top thereof and extending laterally therefrom, and said `point portion comprising a longitudinally-extending web rising from the base plate and having a tapering head formed on the top thereof andJ extending laterally therefrom.

4. In a railroad frog, a steel casting forining a base plate, a point port-ion anda wing railv adjacent one side of the point portion, said wing rail' comprising a longitudinallyextending web rising from the base plate and having a head formed on the top there- The ends of and extending laterally therefrom, and said casting forming transversely-extending webs connecting the first named web and the point portion and supporting said head.

5. In a railroad frog, a steel casting forminga1-base plate, a point portion anda wing rail adjacent one side of the point portion,

said point portion comprising a longitudinally-extending web rising from the base plate and having a tapering head formed on the top. thereof and extending laterally therefrom, and said casting forming transversely-extending webs connecting said wing rail and the first named web and supporting said head.
